I can echo that it’s far easier than xCAT is (similar to the Warewulf vs. xCAT
comparison). The one place it’s lacking is documentation of certain workflows,
like I’m starting from here and what do I do to get where I’m going (new system
in box, system that already has credentials configured, when you’d want
automatic discovery and what it can do, etc.), so there are some things that I
did that were more work than they needed to be and outsmarted the ways
Confluent was trying to help, but it’s otherwise pretty simple to use.
The other thing that surprised me (I actually replaced hardware over it before
I realized) was that it connects to the IPMI console and stays connected, so
you need to decide whether that’s going to be an issue for anything else you’re
doing as it will tell you that SoL is already in use (you can configure it to
act differently — I just was testing out Confluent and forgot that it did that).

Hello David,
I've been POC-ing the software on RHEL 8.6 using old HPE hardware. So far it's
been fairly simple to get up and running. The documentation is up to date and
the lead developer (Jarrod) has been able to answer my questions. If your fear
is the learning curve then I'd have to advise you might be mistaken. I hope
this is helpful.

Yes, there was perhaps auto-completion with regards Confluent/Confluence.
I currently have a (legacy?) ‘joint’ xCAT-Confluent (3.6) installation on RHEL
7 that I inherited; if one wants to fully move from xCAT to Confluent, is there
document on how to ‘extract’ oneself from xCAT? I don’t see anything that jumps
out at:
https://hpc.lenovo.com/users/
https://hpc.lenovo.com/users/documentation/
Should I simply abandon the previous installation and do a fresh install? While
there is some documentation, the system leans towards being heavily vendor-used
so people completely new to it have a steep learning curve (xCAT is/was also
challenging to get into since it was fairly vendor-focused).
